With its latest micro-mirror-based light-steering chip, Texas Instruments says, applications developers can innovate with more than 4 million micromirrors to enable high throughput digital imaging applications.

Presented as its highest speed and resolution chipset for 3D printing and lithography applications, TI’s DLP9000X digital micromirror device (DMD) and the DLPC910 controller, offers developers more than five times the speed at continuous streaming compared to the existing DLP9000 chipset.

The DLP9000X DMD delivers the highest streaming pixel speed in the TI DLP Products portfolio at over 60 gigabits per second.

Because of their low cost and small size, DHT11 humidity and temperature sensors are perfect for lots of different DIY electronics projects. Some projects where the DHT11 would be useful include remote weather stations, home environment control systems, and agricultural/garden monitoring systems. The DHT11 is a digital sensor that lets you easily get relative humidity and temperature readings in your projects. In this post, I’ll first go into a little background on what humidity is, then I’ll explain how the DHT11 measures humidity. After that, I’ll show you how to connect the DHT11 to the Arduino and give you some example code so you can use the DHT11 in your own projects.

For my monthly maker column in Dutch newspaper “De Volkskrant”, I made a coolbox in which you can control the temperature in three separate compartments to keep craft beer at just the right temperature.

The contraption I build uses three Peltier-elements to cool, an old desktop computers power source, an LCD to show both the measured and the set temperature and finally an Arduino to tie it all together.

The Arduino controls a Geared Stepper Motor 28BYJ-48 via a ULN2003 Stepper Motor Driver Board. The 4×20 I2C LCD display and 5 micro switches form the interface to the Arduino. The controller has a Manfrotto 200PL-14 quick release tripod mount for attachment to my tripod and other mounting hardware fitted with a Manfrotto 323 Quick Release Clamp Adapter. Power is provided by a 50000mah USB Power Bank Battery Pack.

Industruino is a fully featured Arduino Leonardo compatible board housed in a DIN-rail mountable case + prototyping area + onboard LCD + membrane panel. With this product you will be able to permanently install your Arduino application in no-time.

Whether you use it for automation projects, data loggers or an interactive art installation, Industruino offers you ruggedness, plenty of features and low cost.

Wouldn’t it be nice to have an internet-connected alarm clock that automatically sets itself, based on your calendar? You would never miss an early appointment, never forget to set your alarm, and enjoy more restful sleep knowing you’ve solved the nightmare of regulating your alarms. An internet-savvy alarm clock could even watch your inbox and wake you up if friends or family send you an important email.

This S.M.A.R.T. Alarm Clock (Setup for Meetings, Appointments, Reminders, and Tasks) uses the Arduino Yún, which is a special Arduino with two processors. One processor runs an embedded version of Linux and is connected to the internet over wi-fi or Ethernet. The other processor uses the same chip as the Arduino Leonardo microcontroller, allowing the Yún to work with most Arduino shields and accessories. By using the Arduino Yún, this project can talk to complex web services with the Linux processor, and interface with hardware — an LCD touchscreen — on the second processor.

Distributor element14 has a 7-in. Touchscreen Display for the Raspberry Pi, expanding the ecosystem of accessories, to enable users to create all-in-one integrated projects such as turning their Pi into a tablet, infotainment system or embedded project.

Compatible with Raspberry Pi 2, and Raspberry Pi 1 models B+ and A+*, the screen can be used to make ‘Internet of Things’ (IoT) devices with a visual display. Connect the Raspberry Pi, develop a Python script, and create home automation devices with touchscreen capability. A range of educational software and programs available on the Raspberry Pi will be touch enabled, making learning and programming easier.

Designed by the Raspberry Pi Foundation, the 800 × 480 display connects to the Raspberry Pi’s DSI display connector via an adapter board that handles power and signal conversion. Touchscreen drivers with support for 10-finger touch and an on-screen keyboard will be integrated into the latest Raspbian OS for full functionality without the need for a physical keyboard or mouse.

This is the 2nd version of Thermistor Thermometer Project done by another group of my student. The 1st version having 4-digit 7-segment LED shows the use of simple display device. For applications that needs text display, this LCD version is more suitable and easy to adapt for many kinds of measuring devices.

The automotive products are quite recognized nowadays. It brings high demand on automotive chip and other related electronic devices. These demands are diverse, which brings difficulties to automotive developers. In this design, users are provided a modifiable firmware using In-System/In-Application Programming (ISP/IAP) via USB. It features the Vertical Alignment (VA) Chip-On-Glass (COG) display module with integrated backlight. The power supply can be done either via USB or an external power supply. This can also be used for an external VLCD that also provide temperature compensation. Its 100 segment and 18 backplanes allow the system to drive up to 1800 elements for graphic display.

The design is comprised of PCA8539DUG 100 x 18 COG automotive LCD dot matrix driver that generates the drive signals for multiplexed LCD, which in this design it is a Passive Matrix Vertically Aligned (PMVA) negative display providing a very dark background with a very wide and symmetric viewing angle. The NX1117CE low-dropout linear regulator is used to provide 3.3V supply for the backlight and the microcontroller. The LPCXpresso low-cost development platform provides the variety of interfaces with respect to the customer designs or needs. It is a highly integrated software development environment for NXP’s LPC microcontrollers. The JP1 to JP6 are used to select either the I2C – bus interface, or the SPI interface. They need to be all in the same position. The silk screen indicates which position to use for a given interface. The JP7 is a jumper that connects the VLCDOUT and VLCDSENSE to the VLCDIN pin of the PCA8539. It must be placed if the internal voltage generation is used. The JP9 may not have been soldered into the board during manufacturing. Instead, a 0Ω resistor (R2) is mounted, in parallel with this jumper. Removing the 0Ω resistor and mounting the jumper makes it easy to insert a current meter and measure the current consumption to the VDD pins of the PCA8539. After measurements, a jumper header can be inserted. The PMEG3005CT 500mA low VF dual MEGA Schottky barrier rectifier is used for the polarity and stress protection.

The development in automotive is quite helpful to people. It is use to accomplish task, save lives, and protect people from any type of danger. With this new design of automotive LCD, it is expected that automobiles will be able to optimize its usage and capability to serve people
